- Dual certification compliance with both DIN 982 and ISO 7040 standards for international acceptance
Professional Applications & Engineering Value
This M8 nylon insert lock nut delivers critical vibration resistance in high-stress environments where conventional nuts would loosen over time. The zinc yellow-chromate plated steel construction provides excellent corrosion protection while maintaining Class 8 strength, making it ideal for automotive assemblies, industrial machinery, and electrical equipment. The nylon insert locking mechanism creates consistent friction against mating threads, eliminating the need for secondary locking devices and reducing assembly time. Engineered to DIN 982 and ISO 7040 standards, this metric hex nut ensures precise fit and reliable performance in applications subject to constant vibration, thermal cycling, and mechanical stress, while the temperature-resistant nylon insert maintains integrity up to 220°F.
Specification Summary & Compliance
This lock nut features M8 x 1.25mm coarse threading with Class 6H thread fit for precise engagement, measuring 13mm across flats and 9.5mm in height. Manufactured in compliance with DIN 982 and ISO 7040 international standards, ensuring dimensional accuracy and performance reliability. The product meets Class 8 strength classification requirements and incorporates RoHS and REACH compliance for environmental safety. Right-hand thread direction and external hex drive style provide standardized installation compatibility across industrial applications.
